Overview
- Local authorities confirmed isolated cyanobacteria (blue‑green algae) at Vöhringer See and say there is no acute health danger and no bathing ban at present.
- The Public Health Service Neu‑Ulm advises avoiding visible bluish‑green scums, not swimming in cloudy or discolored water, keeping small children from paddling at the shore, and not swallowing lake water.
- Health guidance also urges rinsing and thoroughly drying the body and swimwear after swimming and seeking medical advice for skin irritation, nausea, or diarrhea.
- Separately, reports of increased cercariae (swimmer’s‑itch larvae) at Sendener Waldsee and other local lakes can cause itchy rashes but are not considered a systemic health threat, so officials recommend avoiding shallow, vegetated and early‑morning bathing.
- Local agencies are stepping up monitoring because hot, sunny, low‑rain conditions and high water temperatures favor blooms, and officials may tighten measures if tests show worsening contamination.
